Application and october 1.1904. sesamo. 226,826.

zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain vnew rovements in Dump-Cars, of which the folowing is a specification. My invention relates to that class of dumpcars having dumping.- doors on both sides, means for operating such dumping-doors, and means for enabling the entire load contained in the car to be dumped on one side of the cenl ter'of the car, as desired.-

he principal object of my invention is to provi e a simple, economical, and efficient dum -car.

. :A urther object of the inventionis to provide in a dump-car 'suitable means for enabling the entire load to be dumped upon. one side of the car.

A further objectof the invention is to provide in a dump-car suitable means vfor enabling the entire load to be dumped upon one side of the car throughout the entire length thereof, including that portion over the bolsters and trucks, without the necessity of removing any part of the load by manual labor.

'A further object of the invention is to provide a abling the entire load to be dumped .upon either side of the car or andpart upon the other, according to the manner of adjusting the mechanism for governing the dumping of the load before the o car is aded.

.A further object is to provide a dump-car: with means whereby the entire load may be dumped upon one side or the other, according to the adjustment ernin the dumpinff of the load, and whereby uilt up above the topof the side frames upon the more lightly loaded v1n comb side of the car to equalize the weight thereof.

A further object of the invention is to provide in a dump-car suitable means for enabling the entire load to be dumped upon one side of the car throughout the entire length thereof, including that portion over the bolsters. and trucks, without the necessity of removlng any part of theload by manual labor, mation with suitable means for affording the largest possible outlet-opening and useful Im.

durnp-car withl suitable means for en part upon one side' of themechanism for gov# between the dumping-doors and the bottoms of the side frames when desired.

.Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a sectional elevation of a car constructed in accordance with my improvements, showing the centrally-pivoted partition extending up Ward and outward at an incline on one side of 6 5 the car and the dumping-door on the opposite side of the carin open position, so as to dump the entire load upon the side having the open dumpingdoor; Fig. 2, a plan view of a car constructed in accordance with my improve- 74o ments; Fig. 3, a detail of one of the wormwheels and worms for operating the main operating-shafts, and thereby the dumping-door mechanism connected therewith, showing the worm-wheel in the position in which it would 7 5 appear upon closing the door shown at the left of Fig. 1 and Fig, 4, a similar detail view of the worm and worm mechanism shown in Fig. 3, the wormwheel being in position to release the door and permit it to swing to 8c open position, the stud upon the operatingshaft being shown in full lines at the point where the releasing of the door would take place and `in dotted lines at the point which such stud would reach upon permitting the door to swing to open position.

In constructing a dump-car in accordance with my improvements I provide longitudinal center sills a. and parallel longitudinal sills b, arranged on each side of such center sills, 9o transverse-beams c, supported b such longitudinal sills extending transversely across the car at suitable intervals and having a central car-bottom portion d mounted thereon, end frames e, and side framesf. Dumping-doors g extend longitudinally ofthe car throughout its entire length between the transverse beams and are pivotally mounted upon main operating-shafts L, so as to swing upward transversely of the car to closed postionperoo tween the transverse beams and in contact with Hanges t, which project outwardly beyond the sides of the transverse beams. These dumping-doors are provided with hinges j,

o .suitable bearin s 12 and 13 upon the car- -rotation of the gear-wheel to the right from Asegmental slot into which the stud 6 extends,

lar 5, secured to the shaft on one side of such worm wheel orgear and by means of an ordinar collar (not shown) rigidly secured to suc main operating-shaft upon the opposite side thereof in any ordinary manner.` This collar 5 is provided with a stud 6, and the col lar and -stud enter a suitable recess 7 in the wheel. The recess in the worm-wheel has a central annular portion which extends entirely around the shaft, so as to receive the collar 5 in engagement with its inner surface, and also an outer portion-in the form of a as shown in Figs. 3 and 4. Shoulders 8 and 9 form the ends of the segmental or outer portion of this slot or recess andare ada ted to engage the stud, so as to move it, and t ereby the main o erating-shaft to which it is connected, in either direction. In Figs. 3 and 4 vthis gear is shown as it would appear in elevation on the left of Fi l-in other words, the recessed side of t e worm-wheel 3 is shown in both these figures. In Fig. 4 the gear-wheel is shown in the position in which -1t would appear after being turned to the left the figure, withthe` shoulder 9 in engagement with 'the stud 6 until the shaft n had moved toward the center of the car vor in releasing direction to the top of the inclined portion of the loop. This would permit the door to swing to open position without fur ther movement of the worm-wheel. The swinging of the door to open position would bring the stud to the position shown in dotted lines in Fig. 4, to which position it is free to turn independently of the gear-wheel. The

the osition shown in Fig. 4 will cause the shou der 8 to engage the stud when it reaches the point where such stud is shown in dotted lines in Fig. 4, and the rotationbeing continued will cause the main operating-shaft, with its stud, to be turned to the position shown in Fig., 3, at which point the door will be in closed position, as shown in Fig. 1.

I provide a worm 10 the threads of which mes with the teeth of the worm-wheel already described, such worm being mounted upon and in fixed relation to a rotatable shaft 11, which is in turn rotatably mounted in frame. A han -wheel 14 is mounted, preferablyat the upper endl of this shaft in fixed relation thereto, and a collar 15 is mounted intermediate such hand-wheel and the bearing 13, so as to prevent the downward movement of the shaft, the collar being in engagement with the bearing. The upward movement of the shaftis prevented by the lower`- bearing, which is in engagement with the worm. l

Itis verydesirable that means be provided whereby the outlet openin between the dumping-door and the side sil or side frames may be made as large as possiblewhen del sired, and also to provide means whereby the body-bolster may be arranged underneath the dumping-door portions in such a manner as to permit them to be opened to the desired extent. These body-holsters should be so short as to provide 'a s ace between the ends thereof and the side s1lls or side frames, wherein the dumping-doors may swing. to open and closed positions. complish this, the side sills 5() or bottom portions ofthe side frames are mounted entirely above the transverse beams, so that they do not extend below the floor-level or bottom of the floor. In other words, the space between the ends of the transverse beams is left open is provided made, preferably, of one integral piece of'cast-steel and consisting of a lower In order to ac' in the direction of the side of the car entirely up to the floor-level. Ashort body-bolsterv suspension portion or member 51, an upper compression portion or member 52, inclined end portions 53, forming shoulders 54, (the faces of which en age t e outer surfaces of the outer pair of tral strut portion or member 55, and intermediate strut portions or members 56. These strut portions or members are arranged at suitable distances from each other and extend from the lower suspension member to the upper compression member, forming pockets therebetween for receiving the longitudinal sills. Each of the intermediate strut portions is provided withabearing portion or ocket 57 for receiving the truss-rods 58, an suitable bearings or pockets 59 are provided in the upper compression member outside of the inter mediate strut portions for supportin the trussrods 60.v A plurality of these bo sters are arranged between the transverse beams and the end sills ofthe car and extend beneath `the doors and at a distance from the ends thereof, so that material which may fall from the ends of the doors in dumping the load will notA come in contact with or interfere`with -the bolsters in' any way. These holsters are of less length than the distance between the side frames and havethe upper portions of each end inclined downwardly and outwardly, as shown, so as to not only provide a suitable form 'for resisting the stress and strains to which the bolsters are subjected, but also for the purpose of providing a sufficient space between the ends of the bolsters and the side sills or side frames for 'dumping the load. By being made sufficiently short these holsters permit the dumpingv-doors to extend over such holsters between the ends thereof and the side sills or side frames, as shown, and the doors have am le space between the ends of the holsters andjside frames in which to move to open or closed position. The side frames are, as already suggested, arranged upon the transverse beams, so that they and the sldesills. if any, are entirely. above the level 'ofthe pivongitudinal sills,) a ceny IIC etal point of the doors and do not .f tend beloriT the bottom of the lloor or i itral floor portieri. Combined with the sh #t holsters this `arrangement oi the side ls or side frames affords a very large discharge-openfin order to provide suitable means whereby the entire load may be dumped at one side extend, forming pivots upon which suchl partition may be swung to the desired position. The lower edge of this partition is thus pi'votally mounted' at the center of the car, so as to extend longitudinally throughout the entire length thereof, and is secured. to the central floor portion (Z or to the supportingframework by means of suitable straps 66, having loop portions through which the pivot pin or rod 65 extends, the straps being secured to the central floor-section by means of bolts 67. These straps, together with the looped angle-irons 63 andthe pivot members 65, form suitable hinges by means of which the pivoted partition may be swung into position sb as to extend upward, and outward at an inr eline from the center of .the car to and be" yond the top of the side rtrames on either side olA the car, as desired. The channel-iron 68 serves to protect and strengthen the upper swinging edge of the partition, and it will be noted that the partition is of suliicient width or height to extend-beyond the top of the side `frames a suilicient distance to enable the load to be built up higher than the side frame on the side of the car on which such partition is arranged. This enables the weight of the l'oad on the opposite sides of. the car to be equalized to some extent without unduly lessening the pitch or incline olthe partition. The partition being arranged on either side ofA the car, so as to extend upward and outward from the center at an incline, the opening oi the dumpingdoors on the opposite side will cause the entire load to be discharged at one side of the center of the car without the necessity of manually handling any part of the material to be dumped.
